I agree - this is painful.
For me it's quite difficult to continue to offer advice for two reasons. The first reason is that I have no idea what's wrong; the second is that I don't have direct access to your environment, so it's much harder and slower to search for the clues and patterns that should lead to a solution.
Please can you open Resource Monitor, reproduce the problem, wait for 30 seconds (or until the graphs fill), then provide screenshots of the CPU, memory, disk and network tabs in Resource Monitor. Please sort the processes and services by usage from most to least (ie. for the CPU tab, click on the CPU column) so that I can clearly see the top consumers. Please also make the window as large as possible so that I can see as many processes and services as possible.
Second, please use LatencyMon to check the DPC/ISR latency on the system. In theory if the hardware and driver versions are truly identical to the other clients then LatencyMon shouldn't show a problem. However all assumptions need to be tested. If LatencyMon does identify a problem, please grab screenshots of each of the sections. Again, please make the window as large as possible, and where relevant apply sorting (eg. in the drivers section, sort by highest execution).
